Formula
The formula used for calculating channel slope is:
Example Solve
Consider an example where:
- Elevation at Point 1 = 100 meters
- Elevation at Point 2 = 50 meters
- Horizontal Distance between Points = 200 meters
Using the formula:
Therefore, the channel slope in this example is −0.25−0.25 meters per meter, indicating a downward slope.
FAQs
